Break Duo 5600 and 7000 Twin Offer Double Filtration for High Productivity

ADG Solutions, distributor for Break Machinery, announced the development of the Duo double filter system, enabling productivity up to 24,000 lbs/hr. The self-cleaning system is suitable for fine or coarse filtration.

Duo is equipped with two perforated discs (‘breakers’), thus increasing the filtering area and production volume. The scraper disc, placed between the two filters, has blades on both sides and rotates to remove contamination from both surfaces. In addition, its geometry prevents filtered contaminants from reentering the melt. The filter surfaces are constantly cleaned so they can be used for longer periods than what is achievable with conventional systems.

The use of two filters makes it possible to reduce the size of the filtration chamber and to have large filtering surfaces, while the system’s operating principle enables it to work in continuous mode and at constant pressure. Manufactured using high-quality alloy steel and adopting antiwear treatments in the most stressed parts, Duo is designed for high resistance to line pressures (up to 350 bar).

The system is designed to filter various types of plastic materials with high percentages of impurities (up to 15% by weight) and handle different contaminants such as paper, wood, aluminum, copper and more. Maintenance operations and replacement of filters and blades can be carried out without dismantling machine parts.

The new Duo 5600 Twin and 7000 Twin consist of two Duo screen changers of the same size, running in parallel. When it becomes necessary to change the screen in the first machine, the flow of that branch of the line is stopped and production remains active only on the other branch, connected to the second screen changer. In this way, production is not interrupted and the screen can be changed without having to stop the line. The same process is then carried out for changing the screen in the second machine.
